Title: Bias input compensation circuit of operational amplifier
Inventor: TSUCHIYA SATOSHI
IPC: G11C27/02
Filed: 1985-05-02
Abstract: PURPOSE:To remove the errors of operational amplifiers by integrating a bias input current by a dummy operational amplifier and applying the integrated output to the inputs of the operational amplifiers to be compensated through a coupling capacitor to cancel the bias input current. CONSTITUTION:When input switches S6-S8 are closed and reset switches S3-S5 are opened, the operational amplifiers OP2-OP4 integrate input signal currents i1-i3 respectively and output integrated outputs E2-E4. The operational amplifier OP1 is a dummy integrator for compensating the bais current, and at the opening of a reset switch S9, only a current IA corresponding to the bias current flows into the input of the OP1 and the integrated output E1 of the IA is outputted. The output of the OP1 is connected to respective inputs of the amplifiers OP2-OP4 through the coupling capacitors C2B-C4B. Consequently, the errors of the operational amplifiers can be removed.

Title: Variable frequency oscillating circuit
Inventor: OKASHIN YAMATO
IPC: H03B5/36
Filed: 1983-05-30
Abstract: PURPOSE:To increase the variable frequency range together with improvement of stability for a variable frequency oscillating circuit and at the same time to convert this circuit suitably into an IC, by making use of the exponential function characteristics of a transistor (TR) to correct the control current to obtain the linear control signal/oscillation frequency characterisitcs. CONSTITUTION:A current I13 flows to a resistance R11 from an amplifier 13, and as a result the collector current I16 of a TRQ16 is equal to that obtained by multiplying the saturation current Is of the TRQ16 by the exponential function of the difference between the base-emitter voltage a TRQ17 and (I13XR11). As a TRQ19 and a TRQ15 constitute a current mirror circuit 14, the collector current I5 of a TRQ5 is equal to I16. Therefore I5(0) is equal to the value obtained by multiplying the current Is by the exponential function of the base voltage of the TRQ17 when the current I5 is equal to I5(0) when I13=0 is satisfied. As a result, I5(0)/I5 is obtained as the exponential function of I13. Then the current I5 changed in terms of an exponential function from the standard I5(0) to I13. Therefore the oscillation frequency has a linear change to the current I13.

Abstract: PURPOSE: To provide the image processing method and the image processing unit in which a sharp extended image is obtained with high quality at a fast processing speed. CONSTITUTION: A division of an original image with a size of N×N picture elements by a magnification processing section 10 is used for a block and a conversion section 11 applies orthogonal transformation to the block as a unit.

Title: Graphics display device
Inventor: OKI TAKESHI
IPC: G06T15/00
Filed: 1990-04-10
Abstract: PURPOSE:To generate two-dimensional and three-dimensional pictures at a high speed and to display those pictures after synthesizing them by adding a hidden-surface processor for generating the three-dimensional picture after making generation and control common for the two-dimensional and three-dimensional pictures. CONSTITUTION:When a display address is outputted from a display control circuit 6 to a CRT, the luminance data of respective picture elements are outputted from a frame memory 5, and line segment data are outputted from a segment memory 10. In a hidden-surface processor 1, the line segment data are successively inputted from the memory 10 and a hidden-surface processing is exerted upon the data developed to the respective picture elements. Then, the luminance data of the respective picture elements are outputted as the result of the hidden- surface processing. Since the luminance data of the three-dimensional picture is delayed only by one scan line in the processor 1, a line buffer 11 delays the luminance data of the two-dimensional picture, as well only for the same delay as the processor 1. In a synthesizing circuit 8, the luminance data of the respective picture elements of a two-dimensional object outputted from the memory 5 is inputted from one side, and the luminance data of the respective picture elements of a three-dimensional object outputted from the memory 10 is inputted from the other side. Then, both data are synthesized and displayed on the CRT3.

IPC: B41J2/44
Filed: 1989-04-14
Abstract: PURPOSE:To make the intensity of a focused image by each lumiscent dot on a photosensitive medium constant and thereby improve print quality by increasing the light output of each luminiscent dot in each light-emitting element in proportion to the distance from the axis of a lens element. CONSTITUTION:A light output for each unit area is increased by decreasing the area of a Zn diffusion layer 18 of a light-emitting element 5 in proportion to the distance from the axis 13 of a lens element 8. In the meantime, the area of the Zn diffusion layer 18 exposed on the surface of the light-emitting element 5, that is, the area of the light-emitting surface 22, is made constant by adjusting the area covered by an aluminum electrode layer 20. The luminiscent dots 6 positioned farther from the axis of the lens element 8 outputs light of increasing intensity in the mentioned design. Consequently, the intensity of illumination of a focused image on a photosensitive medium becomes almost constant, and the exposure of light becomes uniform. Therefore, the shortage of the exposure of light of a focused image projected to a position away from the axis 13 of the lens element 8 does not occur, and as such the non-deterioration of print quality is ensured.
